LOOM.

SPECIFICATION forming part of Letters Patent N0. 449,297, dated March 31, 1891.

Application filed June 23, 1890. serial No- 356,37l. (No model.)

To all whom it may concern:

Be it known that I, HORATIO A. REMING TON, of River Point, in the count yot' Kent and State of Rhode Island, have invented certain new and useful Improvements in Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference thereon, which form a part of this specification.

This invention relates to take-u p or feed motions for looms, such motions embracing the mechanism used to draw or feed the warp through the loom in the process of weaving, and it is intended to prevent the loom from overfeeding when stopped because of the weft-thread breaking or running out, and also to prevent the operative from manipulating the feed mechanism privately for the purpose of increasing the number of yards woven at the expense of the weight and uniformity of the goods.

In the drawings, Figure 1 shows an elevation of a loom omitting those parts not immediately connected with the take-up motion. Fig. 2 is a top View of that part of the loom where the improvements are located. Fig. 3 shows a front elevation of the same part of the loom seen in Fig. 2. Fig. 4 is an enlarged View of theprincipal parts of the improvements. Fig. 5 shows an enlarged front view of the stand 1' and collar 0" on the shaft 0. Fig. 6 is the same as Fig. 5 with a change in position of some of the parts.

A indicatesthe end frame of the loom.

c is a short inclined shaft placed across the end of the loom and held in bearingsz' t" just inside of the ends of the shaft. This shaft 0 is connected with the crank-shaft gby the mitergears f, so as to revolve at the same speed as that shaft. A worm-wheel j is made fast on the shaft 0 in such a position as to engage in the worm-gear h, held on a short shaft 70, which passes through the end frame of the 100111 and is connected by gearing with the sand-roll, as will be hereinafter explained. A jointed pawl s is pivoted 011 stud s, to the end frame, partly above the wheel h, and passes in back of that wheel, having its front end brought out so as to catch in the teeth of the wheel in front. Where the shaft 0 passes through the stand or bearing 2' a vertical oblong opening is made in the stand to receive a collar 0", which is loose on the shaft. The part of the collar which fits in the bearingt' is cut away so that it forms an'ecoentric, so that when the collar is turned half-round on the shaft the eccentric portion, turning in the stand 1', will raise the shaft and the worm j out of engagement with the teeth of the wheel h. The collar is shown provided with a ball- Weight 0 serving as a handle by which it may be turned, and also to hold it in position after being turned.

In the top view, Fig. 2, B represents the breast-beam of the loom; g, the crank-shaft; c, the side shaft. d is a plate attached to the top of the breast-beam B and projecting out beyond it to hold the shipper b and the castoff lever c, which is pivoted to the outer end of the plate (Z and has its inner end reduced in size so as to pass through a hole in a proj ection on the outer end of the weft-fork plate a, which slides in ways in the plate a,attached to the breast-beam B.

In Fig. 3 is shown the connection of the shaft 7.2, to which the worm-gear h is fastened with the sand-roll e. A gear-wheel w is secured on the inner end of the shaft and engages with a larger geanwheel it, held on a stud bolted to an adj ustablearm 01, attached by a set-screw to the hub of the bearing of the shaft 70. A small gear-wheel 00, made fast to the wheel it, engages with a gear-wheel y, secured to the shaft of the sand roll 2. Through this train of wheels motion is conveyed from the wheel h to the sand-roll z to roll up the cloth and draw the warp through the loom. The speed of the take-up can be varied by the usual system of change-gears.

A short rocker-shaft 7?, held in a bearing on the front of the end frame A, has a curved vertical arm 25, attached to its inner end, and a horizontal arm Z, fast on its outer end, is connected by the jointed parts a m (see Fig. 4) to a yoke 0, loose on the shaft 0.

The vertical arm 2f surrounds the cast-off lever 6 close to where it passes through the weft-plate a, so that when in the ordinary operation of the weft-fork the loom is stopped by the breaking or running out of the filling. The cast-off lever e in throwing out the shipper b will also push back the arm t and throw up the arm Z, which will lift the shaft 0 by drawing on the parts 92, in, and by straightening the joint'release the end of piece m from part b, hereinafter described, and raise the worm 3 out of the teeth of the wheel h, thereby stopping the feedin of the warp instantly. This obviates the difficulty arising from the momentum of the running parts of the loom causing the main shaft to make a turn or two after the beltis cast off by the shipper, when if the feed is not stopped at once the warp will be fed through a short distance without any filling,making it necessary to turn the feed back by hand or make athin place in the cloth, and, to increase the difficulty, the weaver cannot be sure of turning back exactly the distance overrun. To prevent the surreptitious turning of the wheel h atooth or so at a time by the weavers touching and moving up the shaft 0 and wheel h with his knee as he passes back and forth to the different looms he is running, and thereby gaining a little at each time in the length of cloth turned out at the expense of its uniformity, a short spring or bar Z) is attached to the top of the stand 2', with its end projecting over so as to catch on the upper end of the piece m and hold it down, so that the shaft 0 cannot be lifted and the wormwheel disengaged from wheel it withou first releasing the end of piece m from the bar 1). The joint of the piecesnm cannot be straightened and the shaft 0 raised without throwing up the arm Z and through the lever '6 stopping the loom if it is running.

The object of the collar 0" is to raise the.

hold the wheel 7t from running back. By turning the collar 9" to raise the shaft itraises the pawl s by winding up a cord or chain 0', attached to the outer end of the pawl and to the pin c in the collar. A raised projection c on the left side of the opening in the stand 11 serves as a stop for the projection 11 on the collar r to bring up against. When the collar r is turned to raise the wormwheel, as before stated, it also lifts the pawl s by means of the cord or chain attached to the pin 6, so that the wheel it can be turned with one hand in either direction. The joint in the pawl s is to allow the middle of it to drop and shorten back one tooth in the wheel h when lifted by the collar r to countback one pick for the missing thread that stopped the loom.

Having thus described my improvements, what I claim as my invention is 1. The shafts c g, thegears f, worm j, and collar r, with its eccentric end, in combination with the wheel 77. and pawl 3, connected with the collar r by chain 0, substantially as and for the pnrnose set forth.

2. The combination of the shaft 0, wormj, and wheel h, and jointed pawl s, with the jointed connections n m, arm Z, rocker-shaft 7?, arm 2?, spring or bar I), yoke 0, and cast-off lever e, substantially as described.

3. The combination, with the shaft 0, worm j, wheel h, and means for lifting the shaft when it is desired to disengage the worm from the worm wheel, of the spring or oar b, jointed connection on n, and shipper-handledisengaging devices having the arm l in operative connection therewith, substantially as described, whereby the shaft cannot be lifted while the loom is running without caus- STEPHEN OOLVIN, FRED E.
